If you're not crashing, you're not flying hard enough. 

Aliens are tough creatures and can withstand many crashes on their interstellar voyages - but the occasional high-speed encounters with pavement, concrete walls or light posts might put the carbon fiber arms out of commission. Fret not, for with this original replacement you can easily restore your Alien to flying condition.

    Alien 5" replacement arm

    Posted by Ken Martin on Jun 16th 2018

    I bought this to replace an arm on a Ready to Sky Martian II 220mm quad. The bolt holes line up, the arm length is correct, and it is 4mm thick. While not a perfect fit it works just fine as a temporary arm while I'm waiting for the Ready to Sky arm to arrive from China

    5" Impulse alien arms

    Posted by Jason hull on Sep 23rd 2017

    I herd a smarta** make a comment calling the alien old tech, I had to laugh as this is the frame that changed the industry, and it's still is one of the top selling if not The top selling frame, I have four of them and fly the shi* out of them and have yet to break an arm, I've completly totaled a frame and even then the arms was used to rebuild another quad. My point is this set up is solid, the parts are well thought out, I have bought a chameleon and it's still in the baggie it came in for a very simple reason. IMPULSERC ROCKS and so dose the customer service period.

    The Alien is one of the quads that helped me get into FPV. I can now fly fast enough to crash it hard enough to break things. They are very strong and well designed arms for one of the best frames available.
